yeah man, a nug is a nug is a nug, smoke it, if you dont die then your safe, think about it this way, when your heater kicks on for the first time in the fall/winter the smell you get from it is burning dust, and youve inhaled much more of that over your lifetime than the little bit that accumulated on your nug over the past few days, toke, and be merry. i wish i could find some.
